Since the initial landmark study on chiral induced spin selectivity (CISS) effect in 1999, considerable experimental and theoretical efforts have been made to understand physical underpinnings mechanistic features of this interesting phenomenon. As first formulated, CISS refers innate ability materials act as filters for electron transport; however, more recent experiments demonstrate that displacement currents arising from charge polarization molecules lead without need net flow. With its identification a fundamental connection between symmetry materials, promises profound ubiquitous implications existing technologies new approaches answering age old questions, such homochiral nature life.

Chirality-induced spin selectivity (CISS) generates giant polarization in transport through chiral molecules, paving the way for novel spintronic devices and enantiomer separation. Unlike conventional transport, CISS magnetoresistance (MR) violates Onsager's reciprocal relation, exhibiting significant resistance changes when reversing electrode magnetization at zero bias. However, its underlying mechanism remains unresolved. In this work, we propose that MR originates from charge trapping modifies electron tunneling barrier circumvents distinct previous polarization-based models. Charge is governed by non-Hermitian skin effect, where dissipation leads to exponential wavefunction localization ferromagnet-chiral molecule interface. Reversing or chirality alters direction, changing occupation of impurity/defect states (i.e., trapping) – a phenomenon term magnetochiral pumping. Our theory explains why can far exceed ferromagnet molecules violate relation but metals do not. Furthermore, it predicts exotic phenomena beyond framework, including asymmetric induced magnetic fields alone (without ferromagnetic electrodes), as confirmed recent experiments. This work offers deeper understanding opens avenues controlling electrostatic interactions chemical biological systems Some produce polarization, feature termed chirality-induced selectivity.

In chemistry and biochemistry, chirality represents the structural asymmetry characterized by nonsuperimposable mirror images for a material such as DNA. physics, however, commonly refers to spin–momentum locking of particle or quasiparticle in momentum space. While seemingly disconnected, molecules crystals can drive electronic through orbital–momentum locking; that is, be transferred from atomic geometry orbitals. Electronic provides an insightful understanding chirality-induced spin selectivity, which electrons exhibit salient polarization after going chiral material, electrical magnetochiral anisotropy, is diode-like transport. It further gives rise new phenomena, anomalous circularly polarized light emission, handedness relies on emission direction. These chirality-driven effects will generate broad impacts fundamental science technology applications spintronics, optoelectronics, biochemistry.

Significant attention has been drawn to electronic transport in chiral materials coupled ferromagnets the chirality-induced spin selectivity (CISS) effect. A large magnetoresistance (MR) is usually observed, which widely interpreted originate from (dependent) transport. However, there are severe discrepancies between experimental results and theoretical interpretations, most notably apparent failure of Onsager reciprocity relations linear response regime. We provide an alternative mechanism for two terminal MR systems a ferromagnet. For this, we point out that it was observed experimentally electrostatic contact potential on ferromagnet depends magnetization direction chirality. The causes barrier be modified by direction, already equilibrium, absence bias current.

We developed circularly polarized light-time-resolved microwave conductivity (CPL-TRMC) for investigation of the CPL-dependent photoinduced charge carrier dynamics in chiral materials with chiroptical properties. Chiral R- or S-perylenediimide (PDI) molecular thin films were paired handedness-sorted (6,5) and (11,-5) single-walled carbon nanotube (SWCNT) to compose a donor (D)-acceptor (A) system spin-dependent separation process, D-A was examined through linear circular polarization-dependent steady-state time-resolved measurements.
